Leaking ABS P-trap - Can I add more cement to stop leak?
	
	
		I have ABS pipe connecting garbage disposer to pipes that lead to P-trap & lines that go in wall connecting to sewer line.  The sink, disposer & ABS piping was professionally installed about 12 years ago.   The plumber used ABS cement to connect all pieces. So I can not unscrew nuts or whatever they are called.
The leak is small & drips slowly.  Leak is coming out from where 2 pieces of ABS were cemented together.   I wonder if there is an easy fix?  Such as apply more cement?
I've read online instructions to repair use hacksaw to saw off  both sides where P-trap connects.   It is very tight under sink is why I'm asking for an easier way to fix.
Thank you in advance.
